Broadcom GISB bus Arbiter controller
|
|
|
|
Required properties:
|
|
|
|
- compatible: should be "brcm,gisb-arb"
|
|
- reg: specifies the base physical address and size of the registers
|
|
- interrupt-parent: specifies the phandle to the parent interrupt controller
|
|
this arbiter gets interrupt line from
|
|
- interrupts: specifies the two interrupts (timeout and TEA) to be used from
|
|
the parent interrupt controller
|
|
|
|
Optional properties:
|
|
|
|
- brcm,gisb-arb-master-mask: 32-bits wide bitmask used to specify which GISB
|
|
masters are valid at the system level
|
|
- brcm,gisb-arb-master-names: string list of the litteral name of the GISB
|
|
masters. Should match the number of bits set in brcm,gisb-master-mask and
|
|
the order in which they appear
|
|
|
|
Example:
|
|
|
|
gisb-arb@f0400000 {
|
|
compatible = "brcm,gisb-arb";
|
|
reg = <0xf0400000 0x800>;
|
|
interrupts = <0>, <2>;
|
|
interrupt-parent = <&sun_l2_intc>;
|
|
|
|
brcm,gisb-arb-master-mask = <0x7>;
|
|
brcm,gisb-arb-master-names = "bsp_0", "scpu_0", "cpu_0";
|
|
};
